Definitions

  • the invention relates to an apparatus for the fire-sealing of a lead-through for at least one cable or wire through a building component consisting of a framework having arranged on each side of it boards of a fireproof material, preferably plaster, said apparatus comprising an inner pipe, completely or partly filled with elastic fire-resistant foam material precompressed transversely to the longitudinal direction of the pipe, and an outer pipe partly surrounding the inner pipe and being displaceable relative to the inner pipe, the pipes, in the mounted position of the apparatus in a hole being made through the building component each, being intended to be connected at their outer end parts to an outer surface of the building component.
  • mounting frames are moulded into the building components as mentioned above. After the cables and/or wires have been run through the space in a frame this is filled with premanufactured fire-resistant pass pieces or with a fire-protective substance.
  • a lead-through which rigidly joins the two outer surfaces of the wall, can give rise to cracking of the plaster boards and rapid deterioration of the wall. Therefore, a lead-through must have a certain movability while when it is exposed to the heat from a fire-center it, must be tight and prevent hot fire-gases as well as poisonous and/or corrosive gases from the fire from passing through the lead-through.
  • An object of the invention is to provide an apparatus rendering possible a quick and simple mounting of a fire-sealed lead-through in a frame-work wall with a plaster board covering.
  • this is achieved by a premanufactured arrangement comprising two concentrically arranged pipes pushed into each other and placed in a hole made in the frame work wall, the free ends of the pipes each being connected to an outer surface of the frame work wall.
  • the inner of the two pipes is completely or partly filled with an elastic fire-resistant foam material precompressed transversely to the longitudinal direction of the pipe.
  • the arrangement is characterized in that the foam material filling the inner pipe in the mounted position of the arrangement partly extends into the outer pipe and presses against its inner surface and thus seals the gap between the two pipes.
  • FIG. 1 is a sectional view which diagrammatically shows a first embodiment of an arrangement for the fire-sealing of a lead-through according to the invention
  • FIG. 2 shows a second embodiment of an arrangement for the fire-sealing of a lead-through according to the invention.
  • FIG. 1 which in cross section shows a first embodiment of an arrangement of fire-sealing of a lead-through mounted in a wall
  • numeral 1 designates a part of a wall being built on latches (not shown), said wall comprising double wall boards 2, 3 on either side of the latches.
  • the space between the boards is filled with an insulating material such as mineral wool 4.
  • an insulating material such as mineral wool 4.
  • a lead-through 10 has been placed consisting of an outer pipe 5, an inner pipe 6 arranged in pipes, said pipe 6 being filled with an elastic fire-resistant foam material 7 precompressed transversely to the longitudinal direction of the pipe.
  • One of the end parts of the outer pipe 5 has been formed with an outer flange 9, which has been fastened, in sealed manner, to the outer surface of the wall boards 2.
  • an outer flange 9 which has been fastened, in sealed manner, to the outer surface of the wall boards 2.
  • the inner pipe 6 is fully inserted into the outer pipe 5, but after the lead-through 10 has been mounted in the wall boards 2 the inner pipe 6 is retracted until its free end part, through a screw, bayonet or similar socket connection has been joined to a flange 11 inserted from the outer side of the wall into the hole in the wall boards 3, said flange being sealingly fastened to the outer surface of the boards 3.
  • the gap 12 has been made fire-resistant and gas-sealing because a portion 8 of the foam material filling 7 in the inner pipe 6 extends into the outer pipe 5 and presses against its inner surface.
  • FIG. 2 differs from the embodiment shown in FIG. 1 only in that the inner pipe 6 is provided with an integral flange 13.
  • This embodiment requires a greater exactitude when mounting, because the entire inner pipe 6, with its precompressed foam material filling 7 must be fitted into the outer pipe 5 inside the wall. The fitting is made more difficult by the presence of the foam material part 8 which is expanding in free condition, which firstly must be inserted into the outer pipe 5, and against which it presses with the highest possible pressure.
  • the part 8 In order to prevent the part 8, when it is not surrounded by the outer pipe 5, from expanding so much that it is not easy to have it placed in its original position again, it is reinforced with a net of plastic or textile (not shown) which, when part 8 is reasonably expanded, is stretched and prevents further expansion without preventing the part 8 from pressing against the inner surface of the outer pipe 5 with full pressure when in the mounted position of the lead-through. Furthermore, the net is designed in such a manner that it does not prevent passage of the cable through the lead-through.
